What do you call when an ion gain electron?
Anion
A type of bonding in which metal atoms achieve a stable form by sharing its outer shell electrons with other metal atoms
Covalent bonding
is created when one atom donates electrons to another, resulting in the formation of oppositely charged ions that attract each other.
ionic bond
What is the valence electron of the element Fe
8
Which of the following is most stable element
Radon
He devised a system of dot called
Lewis electron dot structure
The octet rule is a principle in chemistry that helps explain the stability of atoms in molecules. Which of the following best describes how the octet rule influences the formation of chemical bonds?”
Atoms lose, gain, or share electrons to have a full outer shell of 8 electrons, achieving a stable configuration.
Which of the following is an ionic compound?
KF
What do you call when an ion loses electron ?
Cation
is formed when an atom loses electrons, resulting in a positive charge,
cation
is formed when an atom gains electrons, resulting in a negative charge.
